X will be our first number, y will be our second.
X+=+X
Y+=+5x
Y-X+=+72
-
Y-X=72%0D%0A%7B%7B%7B5X-X+=+72 <--- Plug in 5X for Y
4X+=+72 <--- Combine like terms
X+=+72%2F4 <--- Divide both sides by 4 to isolate X
highlight%28X+=+18%29 <--- Answer for X
-
Since Y+=+5x,
Y=5%2818%29 <--- Plug 18 in for x
highlight%28Y=90%29 <--- solve for Y
